Donzi 35 ZR Cuddy 2011 vs Donzi Z-21 1987 - Boat Spec Comparison

Q: Which is the larger boat — the Donzi 35 ZR Cuddy 2011 or the Donzi Z-21 1987?

The Donzi 35 ZR Cuddy 2011 is the longer of the two at 35,3 feet overall. The Donzi Z-21 1987 comes in at 21,0 feet, making it roughly 14,3 ft shorter — a meaningful difference in deck room and overall on-water presence.

Q: Which boat can handle a bigger outboard?

The Donzi 35 ZR Cuddy 2011 is rated to a maximum of 1 200 hp, giving it the larger power ceiling. The Donzi Z-21 1987 tops out at 350 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.

Q: How many people can each boat hold?

The Donzi 35 ZR Cuddy 2011 is Coast Guard rated for 10 passengers, while the Donzi Z-21 1987 is certified for 6. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.

Q: Which boat has the larger fuel tank — the Donzi 35 ZR Cuddy 2011 or the Donzi Z-21 1987?

The Donzi Z-21 1987 has the bigger tank at 66 gallons, versus 17 gallons on the Donzi 35 ZR Cuddy 2011. That 49-gallon difference translates to roughly 147–245 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Donzi 35 ZR Cuddy 2011 and Donzi Z-21 1987 from the same manufacturer?

Yes — both the Donzi 35 ZR Cuddy 2011 and the Donzi Z-21 1987 are built by Donzi. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.

Detailed Evaluation & Buyer Recommendation

Donzi 35 ZR Cuddy 2011 vs Donzi Z-21 1987 — Same Brand, Different Boat

The Donzi 35 ZR Cuddy 2011 vs Donzi Z-21 1987 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

The power gap is worth calling out. Rated to 1 200 hp, the Donzi 35 ZR Cuddy 2011 has a 850-hp advantage over the Donzi Z-21 1987's 350-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Donzi Z-21 1987 carries 66 gallons versus 17 gallons in the Donzi 35 ZR Cuddy 2011. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Donzi 35 ZR Cuddy 2011 is rated for 10 passengers, while the Donzi Z-21 1987 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Donzi 35 ZR Cuddy 2011 could be the deciding factor.

Bottom line: Choose the Donzi 35 ZR Cuddy 2011 if your priority is putting more people on the water — it handles 10 passengers and at 35,3 ft it has the deck room to back that rating up comfortably. The Donzi Z-21 1987 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
